Are sealed windows a requirement for converting a storage shed into an office?

You need sealed windows installed in your storage shed-turned-office, to protect your office equipment, furniture, and important papers from cold air, moisture and extreme heat leaking through the gaps. Sealed windows provide added insulation protection to a shed, that will get cold during the winter months, even with the heater on. Aside from sealing your windows, get extra protection by double glazing your glass, to protect you and the important documents in your office from harmful UV rays. It is your well-planned and skillfully built insulation that will keep you warm in your shed-office during the colder months.
